Abstract:
World food production is adequate to feed everyone on earth, but the United Nations Food and Agriculture Organization (FAO) has estimated that 1/3 of that food production is lost or wasted. Food is lost at every stage of the food supply chain, from initial agricultural production through to final consumption. Although the 1/3 figure is relatively consistent, worldwide, the mechanism of food losses differs between medium and high-income countries and low-income nations. Food losses in low-income countries tends to be early in the supply chain due to limitations in transportation and storage, while losses in high-income countries tends to be more food waste, when edible food is discarded by the final consumer (households, restaurants and food service). The term food losses can include all losses or relate to supply chain losses; food waste is defined as discard of edible food.
This GHI webinar is organised by the GHI Post-Harvest Losses working group and will be chaired by Dr. Diana Bogueva who is GHI Working Groups Director.
Food Is Never Waste: A Wake up Call to Alleviate Food Insecurity in the Arab World
Professor Dr. Hussein F. Hassan, Department of Natural Sciences, Lebanese American University, Lebanon
Abstract:
According to the United Nations Environment Programme, more than a third of food produced worldwide is wasted. This amount of wastage is enough to feed 2 billion people, while more than 800 million people in the world are hungry. On the consumption level, 61% of food waste takes place in households, 26% in the hospitality sector, and 13% in retail markets. Understanding attitudes and behaviours towards food waste among different stakeholders, in addition to quantifying and characterizing it, is key to address the food waste problem as this is required to establish a baseline, which is highly needed for effective interventions. In the Arab World, only one country, Saudi Arabia, has developed such a baseline. In our presentation, facts and figures on food waste in the Arab World, along with regulations and initiatives on the topic are presented, along with recommendations and take-home messages to mitigate the generation of food waste.
Reducing Post-Harvest Food Losses in the Supply Chain and a Program to Reduce Food Waste at its End
Dr. Kenneth Marsh is Chair of the GHI Post-Harvest Losses working group and Executive Director of the Woodstock Institute for Science & the Humanities in Clemson, South Carolina, US, a not-for-profit organization working to reduce world hunger by cutting food losses.
Abstract:
Reducing Post-Harvest Food Losses: Food losses occur throughout the supply chain and are exacerbated by limitations in that supply chain. Many so-called Less Developed Countries (LDC) have recognized this problem and created institutes to reduce these losses. These institutes create appropriate means to reduce food losses but vary greatly in their participation in UN language scientific media and international conferences, so many of these developments remain in their country-of-origin. Cooperation and exchange of already developed technologies would be a cost-effective way to utilize more of total food production This webinar hosted by the GHI Post-Harvest Losses working group will explore how to promote international exchange of post-harvest technologies in a culturally appropriate manner, with the aid of food and packaging experts willing to volunteer their time to help.
Reducing Food Waste: In countries with sophisticated distribution systems, primarily North America and the European Union, food loss is primarily food waste. Reducing food waste requires a new way of thinking. A system will be proposed that requires people and institutions to discard food waste in a manner that allows the nutrients to be utilized while making the quantity of that waste more visible. A municipality willing to pilot the concept will require that all food waste, ideally household and commercial, be discarded in reusable or biodegradable containers that will be sold and collected by the municipality and converted to compost that could be used by the city and its residents.. As volumes of food waste become recognized, food waste should reduce with savings to both city and residents.
Food Processing and Packaging for Shelf-life Extension and Waste Reduction
Professor Dr. Theofania Tsironi from the Agricultural University of Athens, Greece and Co-chair of the GHI Post-Harvest Losses working group.
Abstract:
Large amounts of food are wasted in the food supply chain. It has been estimated that more than 30% of the produced food is annually discarded. An important cause of food waste is expiring “best-before-date” at the consumer level. The spoilage mechanism, which defines the quality deterioration rate and shelf life of a food product, depends mainly on food composition, treatment, packaging and storage conditions. Nowadays, the development of new food processing and packaging methods or novel combinations of existing technologies shows the potential to achieve shelf life extension of food products, improve management and reduce food waste. Since temperature is one of the most important factors influencing microbial growth and quality parameters, the temperature fluctuations that occur during food transportation and storage before delivery to the consumer can affect significantly food quality and shelf life. Thus the effective control of the cold chain and quality monitoring of food at any stage of the supply chain may result in shelf life management and extension. Developing novel and efficient packaging solutions to improve food quality and shelf life and reduce food waste while not raising the amount of packaging waste is a major challenge during improving the sustainability of food supply chains.
